A so-called contact winding roller is configured with an expandable profile in order to ensure that rolls of paper in roller cutter do not slip during the winding process.

The clamping pressure is adjusted by EP controller. For example, the more clamping pressure is, the bigger tension of the paper is stretched. The tension is varied with the sorts of the materials of paper. Also, the pressure sensor or location sensor responds to the tension changing and transmits it to the PLC as a feedback signal in aiming to regulate tension pressure accordingly.
